Question

Please help write in batch:

On disk c:\ I have folder named test;
in this folder I have subfolders with different names.
I need batch command to loop through all subfolders, and look for files named “Log” and/or “sqlite.sql”; if those files size < 0 Kb or do not exist then delete this subfolder with all files without prompt.

for each sub in Test
 if Isfile("Log") or Isfile("sqlite.sql") and EachFileSizes > 0 Then 
 Else
 Sub.delete
 End If
next

Answer 1

The solution to this problem depends on the place of the subfolders. If they all are directly under C:\test (just one level deep), then this is the solution:

@echo off
setlocal EnableDelayedExpansion
cd C:\test
rem Process all subfolders
for /D %%a in (*) do (
   rem Initially, set to delete this subfolder
   set delete=yes
   rem Confirm that
   for %%b in (%%a\Log %%a\sqlite.sql) do (
      set size=%%~Zb
      if !size! gtr 0 set delete=no
   )
   if !delete! equ yes (
      ECHO rd /S /Q %%a
   )
)

If subfolders may exist several levels deep beneath C:\test, then the solution is much more complicated.
